Following a request by the Premier of South Australia an inspection of the Leigh Creek Coalfield was made on December 5th to December 8th, 1941. My opinion was sought chiefly on the probability of there being a considerable tonnage of coal available which could be won by open cut mining, preferably from one section of the field, near Telford Siding.

This data package contains seismic and potential field data from surveys conducted by GA in the area of the Capel and Faust basins, approximately 800 kms due east of Brisbane. Some of the datas available in this package are: - Survey S302 migrated data - Full PreSTM stacks no Scaling; Full PreSTM stacks with Dual Gate AGC Scalars; Full PreSTM stacks with Dual Gate AGC Scalars and Inverse Q; Near, Middle and Far angle stacks; Near, Middle and Far angle stacks with Inverse Q; Velocities, Navigation and observers logs - Shell MV Petrel (Shell International 1971) - Reprocessed portions of lines P703 & P704 done in 2006 using a PreSTM processing sequence. - AGSO Survey 177 (Aust- NZ 1996): All of line LHRNR_BA collected as part of the Law of the Sea program to establish Australia's extended continental shelf Original + a reprocessed portion of this line done in 2006 using a PreSTM processing sequence. - AGSO Survey 206 "FAUST 1" (Aust - French 1998) 3 lines Original collected as part of the Law of the Sea program to establish Australia's extended continental shelf Original + reprocessed portions of lines 04 & 02 done in 2006 using a PreSTM processing sequence.

The collection is derived from the submission of data under the Offshore Petroleum and Greenhouse Gas Storage Act (OPGGSA) and previous legislation. The Petroleum (Submerged Lands) Act (and the Offshore Petroleum Act & OPGGSA) requires petroleum data to be submitted to the State Designated Authority (DA). These Acts also require the DA's to make copies of the data/samples available to the Commonwealth Minister through the Joint Authority. The collection also contains cores, cuttings, paper reports, logs and stratigraphic cores drilled by BMR and a limited collection of water bores and engineering cores from around Canberra.

All available processed seismic data and well completion reports relevant to the 2009 Acreage Release. Datasets available in Geoframe, Kingdom and Landmark workstation formats.

The Browse Basin lies offshore from Western Australia's Kimberley region and hosts vast accumulations of gas and condensate, making it Australia's next major gas producing province on the North West Shelf. This presentation provides a summary of three areas of the basin where significant petroleum accumulations have been encountered. A summary of the regional geology, evolution and tectonic development of the basin is provided along with a discussion concerning the petroleum potential and reserves of the basin.

In 2021, a total of 21 areas were released for offshore petroleum exploration. They are located in the Bonaparte Basin, Browse Basin, Northern Carnarvon Basin, Otway Basin, Sorell Basin and Gippsland Basin. Despite COVID-19 negatively impacting the industry, participation in the acreage release nomination process was again robust, however, as has been the case in recent years, industry interest is focussed on those areas that are close to existing discoveries and related infrastructure. In tune with the Australian government’s resource development strategy, the areas being offered for exploration are likely to supply extra volumes of natural gas, both for export to SE Asian markets and domestically to meet the forecasted shortage in eastern Australia. According to the 2019 implementation of a modified release process, only one period for work program bidding has been scheduled. The closing date for all submissions is Thursday, 3 March 2022. Geoscience Australia continues to support industry activities by acquiring, interpreting and integrating pre-competitive datasets that are made freely available in the context of the agency’s regional petroleum geological studies. As part of a multidisciplinary study, new data, including regional seismic and petroleum systems modelling for the Otway Basin is now available. Also, a stratigraphic/sedimentological review of the upper Permian to Early Triassic succession in the southern Bonaparte Basin has been completed, the results of which are being presented at this APPEA conference. Large seismic and well data sets, submitted under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGSSA) are made available through the National Offshore Petroleum Information Management System (NOPIMS). Additional data and petroleum related information can be accessed through Geoscience Australia’s data repository. Appeared in The APPEA Journal 61(2) 294-324, 2 July 2021

The Australian Petroleum Source Rocks Mapping project is a new study to improve our understanding of the petroleum resource potential of Australia's sedimentary basins. The Permian source rocks of the Cooper Basin, Australia's premier onshore hydrocarbon producing province are the first to be assessed for this project. Quantifying the spatial distribution and petroleum generation potential of these source rocks is critical for understanding both the conventional and unconventional hydrocarbon prospectivity of the basin. Source rock occurrence, thickness, quality and maturity are mapped across the basin and original source amount and quality maps prior to the onset of generation are calculated. Source rock property mapping results and basin specific kinetics are integrated with 1D thermal history models and a 3D basin model to create a regional multi-1D petroleum systems model for the basin. The modelling outputs quantify both the spatial distribution and total maximum hydrocarbon yield for ten source rocks in the basin. Monte Carlo simulations are used to quantify the uncertainty associated with hydrocarbon yield and to highlight the sensitivity of results to each input parameter. The principal source rocks are the Permian coals and carbonaceous shales of the Gidgealpa Group, with highest potential yields from the Patchawarra Formation coals. The total generation potential of the Permian section highlights the significance of the basin as a world class hydrocarbon province. The systematic workflow applied here demonstrates the importance of integrated geochemical and petroleum systems modelling studies as a predictive tool for understanding the petroleum resource potential of Australia's sedimentary basins.

The folloing metadata covers the datasets within the 'SEEBASE' directory on the CD-ROM and is a sub-set of an external product delivered to Geoscience Australia. This product was created by FrOG Tech (Formerly SRK Consulting Energy Services). It is not an official Geoscience Australia (GA) product. It has not been through the production validation regimen, nor has it been tested by GA for its data completeness, correct spatial representation, attribute accuracy, logical consistency, metadata completeness and correctness. What is SEEBASE? 3D Image of Southern Margins SEEBASE (Structurally Enhanced View of Economic Basement) SEEBASE is a depth-to-basement model that represents the culmination of a number of calibration and integration steps: Integrated structural/kinematic interpretation Geophysical modeling Seismic & well calibration Integration of tectonic events & responses SEEBASE defines basin architecture, and forms the basis for the systematic evaluation of exploration strategies. SEEBASE provides a foundation for petroleum systems evaluation, including play element distribution (source/reservoir/seal), migration pathways, zones of structural complexity, trap distribution, trap type & integrity, Palaeogeography, oil vs. gas distribution, etc.

The data lists the occurrence of selected (only zonally or environmentally significant species of foraminfera were recorded) species of planktic and benthic foraminfera in each dredge sample, denoting that the species is present.
